TRUCK FOR RAILROAD-CARS AND THE LIKE.

weenie.

To all whom it may concern:

Be it known that I, KARL Drnounrz, subject of the King of Sweden, and residing at Arliif, Sweden, have invented certain new and useful Improvements in Trucks for Railroad-Cars and the like, of which the following is a specification. I

In ordinary car trucks with four or more wheels the truck frame is generally supported by springs of one type or another placed directly between the frame and the axle boxes. The car truck can also be provided with equalizers resting directly on the axle boxes and by means of springs connected with the truck frame upon which the car body rests by means of springs. Through these arrangements however the jolting of the car on account of irregularities of the track and the like is. only partly obviated and besides the different parts not the truck are subjected to a great strain through the continuous jolting and the shocks.

The object of this invention is to remedy these inconveniences by means of springs or thelike placed directly between the ends of the equalizers and the axle boxes while the truck frame is suspended on the equalizer by means of springs.

By my invention the joltings and shocks from the irregularities of the track and the joltings on account of the lateral motion in curves and the like are eliminated by different devices, as the equalizers and springs carrying the equalizers are not influenced by the lateral motion, the brake mechanism or the like.

The invention is illustrated on the accom-. panying drawings.

Figure 1 shows one end of the truck in elevation, Fig. 2 is a section through ab in Fqg. 1, and Fig. 3 shows a'planview of the arrangement and also the end of the e ualizer in elevation. Fig.4'shows the w iole truck in elevation in a smaller scale and Fig. 5 shows the swinging bolster by means of which the car body is suspended.

The car body rests in the usual way upon the frame 1 by means of the cross bar 10 the ends of which rest upon the plate springs 11. These latter plate springs 11 rest upon a beam 12 which is supported in the frame 1 by means of the link bars 13. The side pieces of the frame 1 may be made of twospecial shaped bars placed alongside of each other between which the" equalizer 2 is arranged. The upper [side or the equalizer Specification of Letters Patent.

is consequently placed on a level with the frame 1 and at its ends it is shaped into caps 3 placed right over the center of the journal 7 and here Trestin upon suitable springs 4 arrangeidirect y\between the boxes and tlie emsofltlieiqqualizers which furnish the-primary mpi 'oflfiuspension upon the axle-boxes. Insideof' i and close to the boxes the frame ported by the equalizers, in thisffca means of intermediate springs 7 which a e connected with the equalizer and frameby bolts -6, washers 5, 8. andfnuts 9. Thus as shown in Figs. 1, 2 and'fr3, the equalizer is s sup attached to the axle-boxes by the springs 4. Each end of the equalizer has a bolt 6 .fixed thereto, the lower end of the bolt having a washer 8 which rests upon the-lower end of the spring 7. The equalizer 2 and the frame 1 are thus connected by the spring 7. By this arrangement the lZrame 1 is elastically supported by the springs. 7

which are suspended from the equalizers types are used.

Of course, the different detailsmay be arranged in many different ways without the invention thereby losing its character, i. e. the arrangement of springs or the like placed directly between the axle boxes and the equalizers.

1.- In car-trucks, the combination of equal izers, springs directly between said equal:

izers and the axle-boxes of 'said trucks, the

frame of said trucks being composed of parallel members between which the equalizers are arranged, the ends of the equalizers rests ing against said springs placed directly be tween said equalizers and said axle-boxesf 2. In car-trucks, the combination ofequalizerS:- springs intermediate said equalizers and the axle-boxes" of said truckaga't'rfick frame, said, truckfrarne being connected to.

said equalizers by springs, the side parts of said truokirarne consisting gt'oarallel (members between' which the equalizersnre mediate said equalizers and said axle boxes "ar'rpnged, the ends ofsaid equalizers being bearing the entireweight of said equalizers formed into caps. v and of said truck-frame, said' equalizers 15 .3.
